SEALING PRESS.

Application filed February 26, 1927.

This invention relates to a sealing press,

The purpose of this invention isto pro- Vide efficient and inexpensive means for holding the handles of the tool reliably in a closed position when not in use and yet permit of easily and conveniently releasing these handles when it is desired to operate the tool.

In the accompanying c rawings:

Figure 1 is a side elevation, partly broken away, of a sealing press and embodying my improvements. Figure2 is a top plan view of the same. Figure 3 is a cross section taken on the line 33 of Fig. 1. Figure 4 is a fragmentary side view of the upper hand lever of the press showing the cutter blade mounted on the same. Figure 5 is a perspective view of the cutter blade mounted on the upper hand lever of the tool.

Similar characters of reference indicate like parts in the several views of the drawings.

The frame of this tool comprises two side pieces or cheeks 10, 10, which are spaced apart, and a cross piece 11 connecting the lower parts of said side pieces and constructed integrally therewith. Arranged within the frame and the central parts of its side pieces is a lowerlever which is pivoted between its front die arm 12 and its rearwardly projecting handle 13- to the side pieces of the frame by a transverse pivot bolt 1st.

On the lower part of the frame the same carries a lower die 15 and on the front arm of the lower lever is mounted an upper die 16-which co-operates with the lower die for compressing a lead seal disk and securing a sealing wire therein. The lower lever is turned in the direction for separating the upper and lower dies by a spring 17 interposed between the cross piece of the frame and the front arm of the lower lever.

Arranged between the upper part of the side pieces of the main frame is an upper lever which has a hub 18 pivoted to the side pieces by a transverse bolt 19, a handle 20 projecting rearwardly from the hub and a cam 21 on its inner side engaging with the outer side of the front arm of the lower lever. By pressing the handles of the upper and lower levers together the cam of the upper lever acting on the front arm of the lower lever will force the upper die toward the lower die and produce a compressing effect on the lead seal disk which is placed between the dies.

Serial No. 171,285.

In the preferred form of my invention each of the side pieces of the frame is provided at its upper side with a notch 22, the rear side 28 forms a cutting edge, said notches being-arranged transversely in line. The upper front part of the hub of the upper lever is provided with cutting edges 24 which co-operate with both cutting edges of the side pieces of the frame for severing a wire placed across said edges. The cutting edges 2 1 may be formed either directly on the hubof the upper lever at opposite ends of a notch 25 therein, in the same manner in which the cutting edges 23 are formed, as shown in Figs. 1 and 2, but it is preferable to form the same at opposite ends of the front side of a notch 26 which is arranged in a cutter block 27 mounted on the upper lever. Although this block may be secured to the upper lever in any suitable manner this is preferably accomplished by providing the upper side of the hub of the upper lever in front of its axis with a notch or socket 28 which is of dovetail form in section and making the external shape of the cutter block also of dovetail form, as shown at 29, and securing this block in said dovetail notch by a driving fit.

Means embodying my improvements are provided on this press and cutter for holding the operating handles in their closed position when not in use. These means comprise a longitudinally extending guide loop 30 arranged on the upper or handle of the lower lever and a retaining ring 31 slidable lengthwise with its lower part on the guide loop while its upper part is adapted to he slid lengthwise forwardlv over the handle of the upper lever for the purpose of holding the handles together, as shown by full lines in Figs. 1 and 2, or to he slid backwardly oif from the upper handle, as shown by dotted lines in Fig. 1, so as to release the handles and permit them to be separated.

In order to prevent easy backward movement of the retaining ring on the upper handle and thereby prevent accidental re lease and separation of the handles which would render it inconvenient to carry or store the same detent means are provided which preferably consist of a convex face 32 formed lengthwise on the outer side of the handle of the upper lever and a convex face 83 formed lengthwise on the underside of the loop on the handle of the lower lever,

inner side of the is moved forward on the loop and the upper;

this ring, loop and upper handle willhandle, be sprung slightly in order to permit the ring to slip forwardly over the summits of the convex faces on the loop and the upper handle and then the'resilience of these parts holds the ring in its foremost or operative position shown in Fig. 1. By forcin the retaining ring backwardly with StlfilClGIlli pressure to overcome this resilience the ring can he passed over the salient parts of the convex faces of the loop and upper handle for uncoupling the handles and permit of using the tool either for in'ipressing the lead disk of a seal or cutting the wire of the same. 7 i

The means of holding the press and cutter in their closed positions are very simple and efficient and capable of being manipulated easily and quickly when required.

I claim as my invention:

1. A sealing press comprising a frame, a lower lever pivoted on the central partof said. frame and having a rearwardly projecting handle, an upper lever pivoted on the upper part of the frame and having a cam engaging the lower lever and provided with a rearwardly projecting handle, cooperating dies arranged on the front part of said lower lever and the lower part of said frame, a longitudinal loop arranged on the inner side of the handle of said lower lever, and a retaining'ring sliding with its lower part lengthwise on said loop and adapted to be slipped with its upper. part lengthwise into and out of engagement with theouter side of the handle of said upper lever.

2. A sealing press comprising'a. frame, a lower lever pivoted on the central part of said frame-and having a. rearwardly projecting handle, an upper lever pivoted on the upper part of the frame and having a cam engaging the lower lever and provided with a rearwardly projecting handle, cooperating dies arranged on the front part of said lower lever and the lower part of said frame, a longitudinal loop arranged on the inner side of the handle of said lower lever, and a retaining ring sliding with its lower part lengthwise on said loop and adapted to he slipped with its upper part lengthwise into and out of engagement with the outer side of the handle of said upper lever, the upper side of said upper handle being of convex form lengthwise thereof.
